New research suggests that even minor increases in daily physical activity, such as climbing stairs or quick bike rides, can meaningfully reduce blood pressure. Just five minutes of additional daily exercise could contribute to improvements, according to a study by University College London (UCL) and the University of Sydney, published in Circulation. Supported by the British Heart Foundation, the research analyzed health data from 14,761 participants equipped with wearable activity trackers, highlighting the importance of brief, routine bouts of exercise in blood pressure management.
The study examined six types of daily behaviors, ranging from sedentary activities like sitting to more vigorous exercises, including cycling and stair climbing. Researchers found that swapping five minutes of sedentary time for exercise could decrease systolic blood pressure (SBP) by 0.68 mmHg and diastolic blood pressure (DBP) by 0.54 mmHg. While these reductions may seem small individually, at the population level, such changes could result in a roughly 10% decrease in cardiovascular disease risk.
The results suggest that engaging in just 10 to 20 additional minutes of moderate to vigorous exercise daily could lead to “clinically meaningful” blood pressure reductions, particularly for those looking to reduce their cardiovascular disease risk without relying solely on medication.
This study emphasizes that even short bouts of exercise can have lasting cardiovascular benefits. High blood pressure, or hypertension, affects 1.28 billion adults worldwide and significantly increases the risk of heart disease, kidney damage, and stroke. Professor Emmanuel Stamatakis of the University of Sydney noted that while medication is a common intervention, short, manageable increments of physical activity offer an “accessible way” to improve health outcomes.
For those who don’t regularly engage in vigorous exercise, the study also noted that walking can still offer benefits, though moderate or high-intensity activities have the most pronounced effects on blood pressure. Wearable activity monitors could be useful for individuals aiming to track and adjust their movement patterns, as Professor Mark Hamer of UCL explained.
This research reinforces the impact that short, higher-intensity physical activities can have on overall health, even when integrated into daily routines. For healthcare providers, the findings offer new insights into recommending accessible, incremental lifestyle adjustments to patients, which could contribute significantly to public health initiatives targeting hypertension.
With hypertension often called the “silent killer” due to its lack of symptoms, accessible exercise recommendations could be vital in preventive care.
